Drivetrain Forge Blow Off Adaptor For Cooper S Turbo

Forge Blow Off Adaptor For Cooper S Turbo
I've seen post of people running this on their MINI... But can anyone attest as to whether or not it is worth it?
Is there an increased blow off sound over the already increased sound I gained from installing my NM Intake?
Are there any gains from the BOV decreasing the amount of high temp air entering the turbo?
And lastly, has this product triggered anyone's CEL?
It seems fairly priced, and I'm willing to purchase for sound increase alone, but would like to see somewhat of a performance benefit.
Thanks...

I had one of these installed on my 2012 MCS along with the NM intake. The sound it puts out is loud, a little bit louder than running just the intake alone. The main difference between the two was that the sound was just a tad different in tone. Performance gains were non existent, but it did not throw a CEL on the N18 engine.
I had it installed for quite about 5 months. The sound got on my nerves, a bit too much for me. I just recently removed it and replaced the entire diverter valve with Forge's piston style recirculating diverter valve kit for the N18 (P/N: FMDVR60R). This kit with the NM intake is much quieter than even a completely stock setup, and I enjoy it.

The main reason most factory turbo cars have valves that recirculate air into the engine(which honestly, hot air blowing into the intake side is bad for performance, whether a blow off[or adapter] shows noticeable gains or no), is noise. Most typical car buyers/daily drivers are like Tony above me. They don't want to hear noises. I personally don't mind the noise, will do anything I can(within reasonable prices) for my engine's longevity and performance to meet my needs. It is a very loud blow off sound compared to some aftermarket boost-pipe-mounted valves, but I like it. Do a youtube search if you must before buying.
For the price, knowing I don't get a burst of hot air going into the cold side of my engine every time I come out of boost makes me happy. And the sound is to my personal liking.
As for CEL's, none. I've had it on since the beginning of February and haven't gotten one.

I also have RaceChip (piggy back ECU tuning) installed which supposingly increase my boost slightly. Anyway, the Forge diverter kit does makes things quieter for your ride with NM you saying?

I had a good long awesome drive through the canyons in my area (Cleveland National Forest) just north of San Diego, there's a lot of twisty sharp turns with long high speed turns in the middle.
Now for the Forge diverter valve feedback (recirculation valve), what a hyperactive turbo! Whenever I would shift gears, when I was back on the gas pedal the turbo was just waiting for me almost as if it hadn't lost any boost. It almost seemed as though my stock valve never fully closed during boost, that's just the way it felt after trying out the Forge valve.
The Forge diverter valve increases the response of your turbo just like they say it does, the best bang for your buck mod for the money period! I'd even say that perhaps the Forge valve is even more noticeable than my Borla S-Type exhaust system, that's my brother thought. He was there for both installs and the Forge valve has his attention vs the Borla exhaust.
I'm sure both play there part, now I'm looking at a Evolve-R and their 200 cel sport DP/cat. Removing the second cat as well and maybe my Borla resonator.

check engine light on with the bov recirc n18
I installed it last week and keep getting the check engine light in the morning
scanned the fault and it showed me fault code :28BD , throttle valve actuator, closing spring check.
did you guuys like me had to shave part of the electric plug of the kit for it to fit?please I need help thank you

In reply to your question, yes I have to shave off the connector to fit it. And its working beautifully. Have you connect the connector? Engine light should be due to connection not established.

Dont do it if you have the n14 motor... no matter what you do on any mini motor you will throw a CEL... the n14 will go into limp mode (no boost) until you take it out... these systems are very touchy and when they don't get the proper boost recirculated they let you know... there is no remedy for the CEL...
don't get the adaptor and an upgraded BOV confused... the adaptor is trouble and comes from the Volkswagon Audi world... which works flawlessly on them and sounds awesome... however without going into detail, in my experience, if you have the n14 motor it will not work... I had one, it went on and off in 1 night and sent back for a refund... I cannot attest for the n18 motor, I have zero experience with that motor...
unfortunately the best "sound" upgrade will come from an intake as far as the diverter valve goes...

I had the Forge Valve on my MCS R56 & it throws a Cell after about 30 mins of driving. So I don't think the guy is retarded at all, as I can confirm this problem. I have checked my car with a code reader and my car is usually fine with no faults.
Also, the blow off sound sounds more like air leak than what I have heard on Scoobies & Evos.

Are you retarded on purpose or by birth? I have had the adapter on mine for a year now with NO ill effects at all. Many others as well. I don't get why you think a company like Forge would put something out for the N14 that would do that? There would have to be other underlying issues when you put it on, or you don't ACTUALLY have experience with the Forge adapter on your N14.

I had a rough time with it, because the n14 wants to see recirulated boost and the adaptor dumps it to the atmosphere… I threw the engine code (diverter valve error) and went into limp mode… it would only work for a few pulls IN MY EXPERIENCE…
If it works for some people awesome give it a shot… I recommend that you don't, this motor is not designed to run that way…

Are you sure you didn't do something else to it? Damage a sealing O-ring on re-install? Leave something unplugged or not fully tightened? Have a bad diaphragm on the diverter that just finally let itself go with the uninstall and reinstall process? I just have a hard time believing that a part I've been using for a year now that has caused no issues, causes issues on other engines of the same exact type. I don't get how or why that would be. Your 08 shouldn't have any different sensors of computer processes than my 07 in the grand scheme of things.
ALSO, as for "the engine wants to see the recirculated boost", false. These engines do not depend on the blown off, excess air to run properly. They run off a manifold pressure sensor AND MAF, and the blow off from the turbo does not recirculate in a way that metering it is dire in order to get the right fuel/air mix. The car will read whatever actual manifold pressure there is and adjust fuel from there. Because the MAF is not the sole means of measuring air entering the engine, that blown-off air does not NEED to end up back in the engine. The sensor on the intake manifold will see what's THERE, just before entering the engine itself, and adjust the fuel to accommodate.
Like most turbo cars from the factory, it has a recirculator to keep the thing quiet, NOT because somehow it needs it for performance.

I don't believe anyone had a problem with you stating "your experience". I think the problem was with your first, overly broad, statement.
I won't get to installing mine until I get a little warm weather. I have the FM207V. This valve is piston based , with no diaphragm to fail, and of all aluminium construction, it replaces the original unit with a pressure/vacuum operated piston valve that still also retains the desirable OEM ECU control over valve actuation. But, it still dumps excess boost to the atmosphere. This came off another '07 MCS and was working fine when removed because of pending vehicle sale. I have no reason to believe it won't work the same on mine. At $250+ I don't think they'd still be selling them if they didn't work. Again, just My opinion. I will be installing the Forge unit at the same time I'm installing my AEM CAI, BSH OCC, and BSH dual tap (Which will be activating the Forge). I'll post about My personal experience at that time.

If you rip another one you will be in the same boat as us...

You will find more info on it here...
These motors don't like those adaptors... call your dealer and talk to the mechanic he will explain to you why, and what the CEL codes mean... plenty of people have messed with this and he will have herd of a it... I can assure you that you are a very rare case in not throwing an engine code or going into limp mode... Trust me I'm all for this part I wanted so badly for it to work in my car... My best friend had one in his GTI and I called forge the next day after he put his in... however In my case as well as many others, it was just not an option... and it has nothing to do with MAF sensors and A/F ratios...

I do understand how these things work and on these cars, the MAF is not the sole provider of air intake information for fuel adjustments. Venting the excess compressed air to atmosphere on the N14 should not cause an issue. If it's causing an issue for some people, that's odd to me because again, all of our motors are controlled and monitored the same and there are plenty of people without issues. If these cars ran solely off a MAF like an old MR2 or something where you KNOW you're going to mess up the air/fuel mixture by venting to atmosphere that would be one thing. But these companies such as Forge came up with this part knowing that it wouldn't cause issues.
And yes, the only difference between the air recirculating and being vented IS air/fuel metering. What else would the recirculated air possibly benefit? This has nothing to do with the operation of the factory valve, diaphragm issues, or anything like that. It simply spaces the stock valve back, which still works as it did previously, the air is simply rerouted.
